1 GENERAL

1.1Design Principles

This calculation covers the Analysis and Design of steel frame for External GRC Support

3D Space frame Analysis is done with Dead load, Live load, Wind Load

This document contains load calculations, analysis & design of the main structural

steel elements.

1.2Idealization of Structures

GRC framing is idealized as firmly connected with each other and finally connected

with main R.C.C. & solid block-wall system of the building.

1.3Standards and Codes

Structural use of steelwork in building BS5950-1:2000

Loading for Buildings BS 6399-Part I, Part-II & Part-III

Wind Load as per BS 6399 part II: 1997

1.4Units of Measurement

Units of measurement are in SI unless noted otherwise.

1.5Design Inputs

Grade of Structural Steel = S275

Fy = 275 N/mm2

Fu = 400 N/mm2

Modulus of Elasticity E = 205000 N/mm2

Loading for Buildings BS 6399-Part I & III

American Welding Society (AWS) D1.1

Wind Load as per BS 6399 Part-II: 1997

2.2Assumptions

GRC Elements are firmly connected to steel elements and concrete elements

with the mechanical fasteners with min. of grade 8.8 anchors and S275 plates

Gade of fasteners are Min. of 8.8

Grade of Main Steel Elements are Min. of 275 N/mm2

GRC Elements are purly for Architectural Purpose only.

Conclusion:

*Allowable Deflection of all members considered in the design = Span/350 As per BS 5950

(See Stadd output File )

*Members are safe enough to carry loads in both compression and tension.As per BS 56950

( See Stadd Out put file)
